■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as dangerous han-
dling characteristics, which may lead to an a
ccident resulting in death or serious injury.
●Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other than those recommended by Lexus.
●Do not mix differently constructed tires (radial, bias-belted or bias-ply tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
●Vehicles with spare tire: Do not tow if your vehicle has a spare tire installed.
●Vehicles with emergency tire puncture repair kit: Do not tow anything if a tire that has
been repaired using the emergency tire punc ture repair kit is installed. The load on
the tire may cause unexpected damage to the tire.
■When initializing the tire pressure warning system
Do not initialize tire inflation pressure withou t first adjusting the tire inflation pressure to
the specified level. Otherwise, the tire pressure warning light may not come on even if
the tire inflation pressure is low, or it may come on when the tire inflation pressure is
actually normal.
■Caution regarding interference with electronic devices
●Users of any electrical medical device other than implantable cardiac pacemakers,
cardiac resynchronization therapy-pacemakers or implantable cardioverter defibril-
lators should consult the manufacturer of the device for information about its opera-
tion under the influence of radio waves.
Radio waves could have unexpected effects on the operation of such medical
devices.
●People with implantable cardiac pacemakers,
cardiac resynchronization therapy-pacemak-
ers or implantable cardioverter defibrillators
should not come within 17.7 in. (450 mm) of
the tire pressure warning system initiators.
The radio waves may affect the operation of
such devices.

When trouble arises
Indicates a malfunction in the tire pressure warning sys-
tem
→ Stop the vehicle in a safe place and turn the engine
switch off then on again. If the tire pressure warning
indicator flashes for 1 minute then illuminates, there
is a malfunction in the system. Have the vehicle
inspected at your Lexus dealer.
Indicates that the tire position information cannot be rec-
ognized
→Drive for a short while and check if the display
updates.
If the radio wave conditio ns improve, the display
may return to normal. If the tire pressure is still not
displayed after driving for several minutes, stop the
vehicle in a safe place, turn the engine switch off
then on again, and start driving. If the tire pressure is
still not displayed even after repeating this process
several times, have the vehicle inspected at your
Lexus dealer.
Indicates that the washer fluid level is low
→ Add washer fluid.
Except F SPORT models of GS350/GS200t, and
GS F: Indicates that remain ing fuel is approximately
2.6 gal. (10.0 L, 2.2 Imp.gal.) or less
F SPORT models of GS350/GS200t: Indicates
remaining fuel is approximately 2.6 gal. (9.9 L,
2.2 Imp.gal.) or less
→ Refuel the vehicle.

Vehicle specifications
■Temperature A, B, C
The temperature grades are A (the highest), B, and C, representing the tire’s
resistance to the generation of heat and its ability to dissipate heat when
tested under controlled conditions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead to sudden tire failure.
Grade C corresponds to a level of performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of performance on the laboratory test
wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is properly inflated and
not overloaded.
Excessive speed, underinflation, or excessive loading, either separately or in com-
bination, can cause heat buildup and possible tire failure.
